We're looking at setting up a MSMQ system with ~8000 clients and one queue per client. On average the system needs to handle ~2000 messages daily from each client, where the message size will range from 1K to MSMQ Max size (4MB).
Is this at all possible with MSMQ?
I know I'm not providing a lot of details here, but I just want feedback on whether or not anyone has been able to run a similar setup.
Well, broadbrush answer is yes, it will scale out no problem, as its a mature product, on the go for over 10 years.
There are a number of very large implementations out there, banks mostly, like Barclays use it, for I think between 60-90k desktops, but only if it has been correctly designed, and each of your processing boxes has enough memory, and suitable network bandwidth.
As regards messaging throughput, 2k messages a day, is nothing really. I was working in the City a few years ago, where one derivatives f/x app was processing 1600 message/sec.
I can't offer you any advice without specifics, but I hope that helps.
Bob.
